' 2 Claims. -(Cl.f2402) 2 The present invention relates to new anduseful improvements in stenciling attachments for typewriters,- and hasfor its primary object to provide, in a manner as hereinafter set forth,a device of this character comprising a novel construction andarrangement for illuminating the work, whereby the operator may clearlyobserve each letter as it is cut.

Another very' important object of the invention is to provide anilluminated stenciling attachment. of the aforementioned character whichis adapted to be expeditiously. installed for operation on standardtypewriting machines without the necessity of making material structuralalterations therein.

Other objects of the invention are to provide an illuminated stencilingattachment for typewriters which Will be comparatively simple inconstruction, strong, durable, highly eflicient and reliable in use,compact, light in weight, and which may be manufactured at low cost.

All of the foregoing, and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view in front elevation of a stenciling attachmentconstructed and applied in accordance with the present invention.

Figure 2 is a view in longitudinal section through the invention.

Figure 3 is a cross-sectional view.

Figure 4 is a detail view in elevation of the glass platen.

Figure 5 is a detail view in elevation of the transparent printingstrip.

Referring now to the drawings in detail, it will be seen that theembodiment of the invention which has been illustrated comprises anelongated housing which is designated generally by reference characterI, which housing may be made of plastic or other suitable material. Asillustrated to advantage in Figure 3 of the drawings, the housing I issubstantially oval in crosssection. Secured on the ends 2 of the housingI are brackets 3 through the medium of which said housing is firmlysecured in position on the ends of the usual platen carriage 4 of atypewriter.

The bottom of the housing I is open and formed integrally with the endwalls 2 thereof are split rings or loops 5 having apertured ears 6 ontheir ends. The split loops 5 rotatably accommodate the end portions ofa tubular glass platen 1 which isexte-rnally frosted. The end portionsof the platen 1 are internally threaded to receive plugs 8 havingcentral bores extending therethrough for accommodating. the usual platenshaft 9-of the typewriter to which said plugs are secured. Thus, theplaten I is mounted on the shaft 9 for rotation therewith.

Mounted immediately in front of the platen I is a writing strip or barID of comparatively soft, transparent material. The writing strip I0,

which is stationary, is of a cross-sectional shape corresponding to thecurvature of the periphery of the platen I. Screws II secure the endportions of the writing strip I0 between the ears 6 of the loops 5.Thus, the split loops 5 are secured around the end portions of theplaten 'I.

It will be observed that the housing I is mounted at an inclination onthe platen carriage 4. Mounted in the front of the housing I is aninclined window I2, the inner surface of which is frosted. The loweredge of the window I2 rests on the strip I0.

Mounted in the housing I is a plurality of electric lamps I 3. In theembodiment shown, the electric lamps I3 are elongated and said lamps aremounted in sockets I4 which are pro- 1 vided therefor on the. end walls2 of the housing I. vA switch I5 on one of the housing end walls 2controls the electric lamps I3. Reflectors I6 project the light from thelamps I3 downwardly and forwardly through the window I2,

the platen 1 and the writing strip ID. A hinged door I! on the back I8of the housing I permitsv access to be had to the lamps I3.

It isthought that the operation of the invention will be readilyapparent from a consideration of the foregoing. Briefly, the paper, as

at I9, is inserted beneath the platen 1 from the rear thereof, and, saidplaten is manually rotated for feeding the paper forwardly and upwardlyacross the strip I 0. The platen 1 accompli'shes this in conjunctionwith the usual feed rollers of the machine. The external frosting of theplaten I facilitates feeding the paper. A guide bar 20 extendstransversely across the window I2 and is hingedly connected to the endwalls 2 of the housing I for holding the paper I9' against said window.The type of the machine cuts the characters in the portion of the paper[9 which is in contact with the comparatively soft strip or bar I U.Light from the electric lamps I3 is transmitted to the work through thewindow I2, the platen and the strip I0, thus permitting the charactersto be clearly seen by the operator as they are cut.

It is believed that the many advantages of a stenciling attachmentconstructed in accordance with the present invention will be readilyunderstood, and although a preferred embodiment of 1. A stencilingattachment for typewriting machines comprising an elongated housing,

means for mounting said housing in an inclined position on a typewritingmachine adjacent the platen, the lower portion of said housing beingopen, loops on said lower portion of the housing at the ends thereof, atubular platen of light transmitting material rotatably mounted on themachine and, operable in the loops, a writing strip of comparativelysoft,transparent material mounted on the loops and extendinglongitudinally of the platen immediately adjacent thereto, a window inthe front of the housing, and electric lamps in the housing forilluminating the platen, the strip and said window.

2. A stenciling attachment for typewriters comprising an elongatedhousing, means for mounting said housing at an inclination on a.typewriting machine adjacent the platen, the lower portion of thehousing being open, split loops integral with the lower portion of thehousing at the ends thereof, opposed ears on the ends of said loops, atubular platen of light transmitting material rotatably mounted on thetypewriter andoperable in the loops and the lower portion of thehousing, a writing strip of comparatively soft, light transmittingmaterial mounted between the ears and extending longitudinallyrelativeto the platen immediately adjacent said platen, a window in the front ofthe housing resting on said strip, and electric lamps in the housing forilluminating the platen, the strip and thewindow.
